Abstract

A pressure regulator for supplying water to a poultry watering system or the like includes a control assembly for operating the pressure regulator in a normal or "on" mode, an off mode or a flush or bypass mode. A desired operating pressure is set by loading a diaphragm responsive to output pressure changes. Diaphragm movement is transferred by the control system to a valve member cooperating with an inlet orifice. The control system includes a spring captured in a preloaded state between first and second end members, one connected to the valve member and the other connected to the diaphragm. A knob is rotated from a normal "on" position to an off position and a collar pushes the end members together and pushes the valve member against the orifice. The knob is rotated to a flush or bypass position and the collar pulls the end members together and pulls the valve member away from the orifice. The inlet orifice and an inlet port are parts of a removeably mounted inlet member.
